Last night, a small knock started to be audible in the front suspension. today it is a full-blown creak + knock. i guess i am a lucky one since the car is giving me a warning. the noise is very noticeable on the driver side..i checked the tie-rods they seem to be changed not too far ago....the ball joint on the other hand has a slightly torn boot, and is the original....

at the beginning, i thought it this was a sway-bar issue, but is more serious now. i will not be driving of-course until i determine the source of this.....

questions:

1-it is very hard to pin-point the source of the noise, what is the best way to do that ?

2-are ball joints changeable on these cars, or do you need a new control arm? i have read that after a certain year, no were non-changeable......

this is serious, as it escalated significantly since last night, so something is going to give...

advice please ....

thanks,
